On Wrangell's north side is a state historic park where you can see primitive rock carvings believed to be at least 1000 years old. Located 0.7 miles from the ferry terminal , a sign marks the viewing deck with interpretive displays and replicas. Turn right and walk north on the beach about 50yd. Before you reach the wrecked fishing vessel, look for faint carvings on the large rocks, many of them resembling spirals and faces.
There are almost 50 in the area, but the majority are submerged at high tide so check a tide book. Also bring a bottle of water; the carvings are easier to see when wet.
